调制光谱
In MSK modulation, due to the discontinuous slope during the switch time of the phasic path, the dropping velocity of the modulation spectrum is affected, and IJF-OQPSK is introduced to solve the limitation, smooth the phasic path and improve the spectrum.
MSK调制技术中,由于其相位路径在转换时刻的斜率不连续,影响了已调信号频谱的衰减速度,针对这一缺陷引入IJF-OQPSK,使得相位路径平滑,频谱特性有所提高。
